180801 OSC CreLoad PHP MySQL Fix

We need a programmer who is GREAT at reading and making changes on scripts coded by others! We need a fix and we need it FAST. We run a Cre-loaded, OS-commerce website on PHP 4 Linux server. Here is my problem! Every time a customer completes an order we get an error. Please see the 2 jpegs attached for the exact errors. Many orders go through, but some do not! You must complete the task off site and demonstrate the fix before we go LIVE. We can not loose any more business than we already have We are a gift store and need this fixed ASAP. It is the holidays! We live or die NOW. The problem appears to be. Missing oscID= the session numbers... and if it is missing, then it would give us these errors. However you can't remove session numbers without forcing cookies.. and to force cookies http:// and https:// need to be on same domain name. Our is domain http:// www . blab la . com While our https is // www . blab la . safesecureweb .com Could this be an improper application of our online registries? We do not make every customer login with a password, would doing so be an easy fix? We are open to anything? We can not go back to the original developer as we ended on bad terms after much of the work done on the site was completed with errors like this one. PLEASE NOTE: We have a wedding and gift registry on the site and any fixes must keep all the functions associated with this part of our business in tact. Please feel free to PMB questions or details. If you can not complete the assignment in the EXACT agreed upon time, Starting the moment the assignment begins, We will cut you loose and go with someone else. This must be a priority job for you! Thank you. Gropius
